Ferrari F430 Spider Bio Fuel

These days, even hardcore performance cars are scrambing to get into the green scene. At the Los Angeles Auto Show, we saw the Pratt & Miller Corvette C6RS, an E85 capable 600 horsepower supercar. At Detroit, Ferrari has taken the leap as well with its F430 Spider Bio Fuel.

Powered by a 4.3-liter V8 running on E85 ethanol, Ferrari says this eco-friendly Italian stallion produces 10 more horsepower than the standard version (that's a total of 500 horses) and gives a four percent increase in torque. Emissions have decreased too - down five percent in CO2. To prepare its bread and butter V8 for E85 duty, recalibration of the engine's CPU was in order, as was modification to the fuel feed system. Ferrari says its goal is to cut its lineup's total emissions by 40 percent, come 2012.
